Chiron recently launched!

^{"The Booth Brothers are building an iPad app that understands math as it's written."}

^‍

^{📌 TL;DR Chiron is an iPad app that understands math as it’s written - like Grammarly for algebra. The founders are both Oxford math grads, have tutored for a decade, and now they’re creating the future of learning which will be entirely 1-on-1.}

Founded by James Booth & Max Booth

Hey there 👋Meet James and Max - brothers and cofounders of Chiron.

‍

❌ Problem

With AI that’s so great at math, why can’t it teach at near-human quality?

• Math is handwritten ✏️
• Math has to be practiced not read 🧮
• AI is rubbish at spotting your mistakes 🔍

‍

✅ Solution

• Freeform writing on a whiteboard app ✍️
• Accuracy of a calculator with symbolic logic 🔢
• Real-time feedback on every stroke (< 300ms) ⚡

‍

⚙️ How did the Booth Brothers do it?

With tens of thousands of lines of Python and Wolfram Language code. Writing on an iPad, they convert the stroke data to LaTeX, parse it, ask a million symbolic questions about it with reference to the problem’s ground truth (the lines with a blue index), and assess whether it is right, wrong or something in between.

^‍

They do not rely on the vibes of a language model to assess the details of their working - too slow and unreliable. Many students give up on LLMs for genuine collaboration when they mislead them on topics the student finds difficult.

They can handle a lot of math already.

‍

💡 Core insight

The founders tried all the AI tutor desktop formulations they could imagine, but beyond the obvious interface challenge, AI is exceptionally poor at spotting the subtle mistakes students often make. LLMs are great at doing correct math, but much worse at pulling out an error within the many lines of messy student reasoning.

They started performing a symbolic analysis of the student’s working as context for the AI to boost accuracy - but then the founders realized they could give this straight to the student. This was when the brothers started to feel the magic.

^{🤝 So far, every single teacher the founders have demoed the iPad app to in person has immediately started work greenlighting a pilot. Let James & Max know if you can introduce them to any math teachers teaching between Algebra I and Calculus I.}

‍

^{⚡ And you can check out Chiron on the App Store now - or share with any students who might benefit from it! Cheers, James & Max.}
